Space aliens

[Eric the Half a Bee]

We've only been here about a million years. Modern type human about 100thousand years, sending radio waves, tv waves into space about 150years, so people who believe aliens have visited us, how would they know we are here? A radio wave travels at the speed of light, so our signals have only reached about 150light years. The nearest habitable planet is thousands of light years away. So how would they know first of all, our blue planet existed (a tiny dot even only a few 100thousand miles away) and secondly, that life even existed on our planet? And thirdly, wasting the time to cross the vast expanseses to check if there is life on our dot. I believe the universe is teaming with life, but no way has any of that life found its way to earth. Right or wrong alien hunters?

Who's to say they'd be able to decipher our radio waves? Who's to say we've got the technology to discover any messages sent from afar? Life on different planets might be so totally different from what anyone could ever predict. We say water is essential for life. Really? How do we know there are other lifeforms and systems that live on, say, rock dust, or some unknown substance or compound that we could never discover?

This is it I think.

People disbelieve other life outside of earth with certainty, when they can't even master basic mathematics. The human brain is pretty pathetic isn't it?. Animals are more in tune with this earth than us.

"The universe has to have an end" Not necessarily.

We have evolved and improved as a species through the collective contributions of billions upon billions of people down the years.

Then you've Dave from accounts thinking alien life is just a bit silly. So I guess he can comprehend the universe in his one dust sized brain eh?. No one can.

It is more enjoyable to be an optimist than a pessimist on this. It is why we are given imaginations. Not to think of the next dead girl storyline in a danish drama, but something bigger!.

Maybe, just maybe planet earth is another planets hell.

Or even oxygen,maybe they do not require it
